SRAM Rise 60 29in Wheels $1,157.00
Big wheels, little weight.
Of all the wheel sizes out there, the one that probably benefits the most from carbon fiber construction are 29ers. Lowering rotational weight as much as possible on larger wheels can be a game changer on the trail. When SRAM purchased Zipp Speed Weaponry a few years back, it acquired the the carbon rim technology needed to develop the high-tech Rise 60 29in Wheels.
It should be noted that Zipp, a longtime (20 plus years) composite component and wheel specialty manufacturing company, has been building carbon rims for road applications for some time now. This know-how is evident in the asymmetric shape and impact-protecting HS resin coating. The asymmetric shape allows SRAM to use near equal length spokes, creating a stronger complete structure. The rim's layers and 3K weave are enhanced to provide strength where the nipples place the most stress to ensure reliability.
The Rise 60 uses stainless steel and bladed Sapim CX-Ray spokes. These spokes are incredibly strong, aerodynamic, and only weigh a touch more than titanium ones. SRAM uses two-cross lacing with 24 spokes per wheel. This reduces weight and ensures optimal stiffness to resist wheel deflection. The straight pull design eliminates stress-prone bends to which traditional spokes are subject.
The hub shell and freehub body are made of lightweight, 6000 series aluminum. They house sealed cartridge bearings for maximum performance and minimum maintenance. The rear hub uses four bearings and it has an aluminum freehub body to keep weight low. A 54-tooth drive ring gives just under seven degrees of engagement, while three pawls with a saw-tooth profile offer nine points of purchase to give the Rise 60s instant and positive engagement when you stomp on the pedals.
SRAM Rise 60 29-Inch Wheels are intended for cross-country race and marathon use. While they're not tubeless ready, they are compatible with tubeless conversion kits such as Stan's No Tubes. They're available with standard quick releases or with 15QR front and 12x142mm rear. They are compatible with six-bolt rotors and Shimano or SRAM cassettes.
